Syntax

ContainsValue(Value: Variant): Boolean;

Parameters

Example

Sub UserProc;
Var
    Hash: IHashtable;
    i: Integer;
    s: String;
Begin
    Hash := New Hashtable.Create;
    For i := 0 To Math.RandBetweenI(50, 100) Do
        Hash.Add("Key_" + Math.RandBetweenI(0, 100).ToString, "Value " + Math.RandBetweenI(0, 100).ToString);
    End For;
    If Hash.ContainsValue("Value 25") Then
        s := "Yes";
    Else
        s := "No";

After executing the example a hash table is generated, and the "s" variable is set to Yes, if it contains an element with the Value 25 value.
